        우리나라의 외환시장 개입도(介入度) 추정

        이환호,윤경석 한국국제경제학회 1997 국제경제연구 Vol.3 No.3

        우리나라는 1990년 3월 복수통화바스켓제도에서 시장평균환율제도로 이행하였다. 양제도하에서 상이한 원화환율 결정방식을 반영하여 우리나라 중앙은행의 외환시장개입방식에서도 커다란 변화가 있었을 것으로 판단하여 본고에서는 우리나라 불태화 외환시장개입의 정도를 추정·분석하는데에 그 목적을 두었다. 이러한 목적을 위해 장단기 불태화계수를 코크란-오컷 방법으로 추정한 결과, 우리나라에서는 단기에서는 강력한 외환시장개입이 이루어지고 있는 반면 장기에서는 그 효과가 그리 크지 못하다는 점과 복수통화바스켓제도하에서는 개입정책이 강력하게 시행되었으나 시장평균환율제도하에서는 불태화가 제대로 이루어지고 있지 못함을 보여주고 있다.

        Today, it is time that human being should be rediscovered as a being with wisdom and ability to live in the modern civilization and a desirable human type should be rebuilt. to build a desirzble human type, it needs a consciousness reform. For a consciousness reform, human being should be aware of a fact that, firstly, man is a member of one global community, secondly, man lives together in a decocratic society and, thirdy, human relationship should be cooperative one, rather than a competitive one. It is only through this consciousness rfform that man can root out a class ideologism,hegemonism and excousive nationalism and that man can construct a global community, in other words, an Oughtopia in the new millennium, the 21st century. The GCS movemenet is aiming at a human-centered human society. The GCS club cativities are the basic activities to build such a society. In the process of club activities, there could ocdur many crises. Those are diverse from internal crises such as member crisis and club crisis to external crisis. For a cisis management through member and family, it can be solved by member, family of relatives. For a crisis management Through club, staff meeting, member control, small group meeting can solver those crises. Besides, the crisis management can be put into effect by a superior organization or a district headquarters or national headquarters. With the crisis management measures, club members can prevent the GCS club crisis in advance. When in crsis, if the members deploy the second REnaissance movement with Goodwill, Cooperation, Service-Contribution, we will realize a society which is spiritually beautiful, materially affluent and humanly rewarding, in ohter words, humanly human society, cultural welfare society. Therfore, we will have to try our best efforts to costruct an Oughtopia, an ought-to-be society.
